I submit that you are completely wrong on this. Rates of poverty,
jailings, dropouts, parentless children, income, welfare-recipiency,
etc. are not at all correlated with proximity to the post office. But
they are tightly correlated with g.

So basically what you're saying is that no matter how comprehensive
the test, and how powerfully predictive the values are, any test will
tell us nothing. Ultimately, everything about reality can be
measured. That's the whole foundation of science. If God exists, we
will create instruments that can distinguish His influence from other
influences.

You should blame stupidity or neglect before ideology. If I missed
your point, it's probably because it was not stated succintly enough,
and I missed it. But you are summarizing below clearly, thanks.
Person of supposedly high intelligence according to who? All I'm
doing is pointing to the data that Linda Gottfredson, a leading
researcher on IQ, has compiled. I'm merely being a conduit for
someone much older and more learned and expert in this area than I.

Sure. But having a measure of a part that correlates tightly with
dozens of relevant variables is always nice.

I'm not saying it's the entire thing. I'm just saying that if some
variable has known predictive validity, we should use it.

G is a very interesting value which has been defined as what IQ tests
are supposed to measure. The term "intelligence" is somewhat
ill-defined, and as Michael Vassar mentioned, sometimes when you call
somewhat "smart" you actually mean "rich", so there is a lot of
ambiguity in these things. IQ, however, is much more precisely
defined. It doesn't really matter is g is "THE" mechanism of
intelligence or not, a strong predictor of behavior is a strong
predictor of behavior.

I never said that IQ is the only measure we should consider for hiring
people for working towards the Singularity. You pulled that one out
of thin air. My initial post was on the difference between people of
IQ ~150 and IQ ~180, then it led to a discussion of the validity of g
and IQ tests in general. I've only been talking about the facts, not
what we should do because of them. The is, not the ought.

But your POQ idea is false. There is a reason why IQ is used by
thousands of organizations and POQ is not. The US army does not let
you join if your IQ is less than 80, for example. IQ is a very valid
concept, but here you seem to be saying that it's useless. It is
clearly very morally and politically charged, judging from all the
responses I got to calling it a valuable metric. This sociomoral
baggage around IQ impedes scientific study concerning it.

"Intelligence" is a subjective measure. IQ is objective and therefore
gives us more scientific substance to work with. I mainly think of
"intelligence" in terms of sequence prediction.

I agree with this observation, but as I argued before, I excuse myself
from all fault with respect to it. :-)
